The European Commission (EC) announced on February 5, 2013, that it completed its five-year review of the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation. The pre-publication version of the EC’s report states that the EC “will make an impact assessment of relevant regulatory options, in particular possible amendments of REACH Annexes, to ensure further clarity on how nanomaterials are addressed and safety demonstrated in registration dossiers. If appropriate the Commission will come forward with a draft implementing act by December 2013.” The pre-publication version of the staff working paper specifically recommends that, if REACH needs amending “for other reasons,” then “consideration should be given to the introduction of the definition of a nanomaterial in line with Recommendation 2011/696/EU.”
